Publication date

[Richard Jensen]

Does anyone know how the publication date for a dissertation is
determined?  The case in question involves a dissertation approved in
1989, but bearing on the cover 1990, the year the degree was awarded.  I
have encountered both dates in the literature and wonder if there is a
"rule" covering this.  I assumed that the date it was approved (i.e.,
accepted by the graduate committee) was the date of publication.
